For stressed-out city dwellers, silent retreats -- being dubbed one of the biggest "travel trends" of 2013 -- may be the perfect antidote to the constant noise of busy, work-driven urban lives. Although these Walden-esque getaways are not for the faint-hearted (the retreats require days of solitude and zero interaction with technology, in most cases), their restorative benefits are many. Increasingly, travelers seeking relaxation, balance and spiritual renewal are heading to meditation centers from the Berkshires to Big Sur in search of simplicity.
